The real question should be; what's wrong with the people that vote for the GOP? When you compare the GOP to real liberty advocates, like Ron Paul supporters, you find that most benefit from some government program that helps their business or the business industry they work in.
The problem with that is it dilutes free-markets. If you compare the GOP spending and tax reductions with Libertarian or Ron Paul's plans, they look worse than the Democrat's plan compared to the GOP.
Oh well, enjoy more government taxes and spending under the leadership of the GOP and Democrats, it's what the Rombama bots wanted. Can't wait until it all implodes.
